Machine tool

Abstract

An injection molding machine according to the present invention is a machine tool that includes a measurement unit that measures a predetermined measured value; a calculation unit that calculates attitude accuracy information about the injection molding machine based on the measured value measured by the measurement unit; and a display that displays the attitude accuracy information calculated by the calculation unit together with an overhead view of the injection molding machine.

What is claimed is: 
     
       1. A machine tool comprising:
 a plurality of measurement units that each measures a measured value; 
 a calculation unit that calculates each of pieces of attitude accuracy information about a base of the machine tool based on each of the measured values; and 
 a display that displays the pieces of attitude accuracy information calculated by the calculation unit together with an overhead view of the machine tool, 
 wherein 
 the calculation unit calculates at least one of levelness, gradient, and verticality as the attitude accuracy information, and 
 the attitude accuracy information is displayed at a position which conforms to an actual position on the overhead view of the machine tool or therearound as a figure representing at least a degree of each attitude accuracy. 
 
     
     
       2. The machine tool according to  claim 1 , wherein the display displays, as the figure, a figure illustrating a bubble level. 
     
     
       3. The machine tool according to  claim 1 , further comprising a determination unit that determines acceptability as to whether the attitude accuracy information is within a predetermined acceptable range, wherein
 the display displays a predetermined display target in a mode differing in response to the acceptability determined by the determination unit. 
 
     
     
       4. The machine tool according to  claim 3 , wherein the display displays, as means for producing the differing mode, at least one of a type of a character indicating the attitude accuracy information and a type of a figure illustrating a bubble level. 
     
     
       5. The machine tool according to  claim 1 , further comprising:
 a sound generation unit that generates sound; and 
 a sound control unit that changes at least one of the loudness of sound and the frequency of sound to be generated by the sound generation unit based on the attitude accuracy information calculated by the calculation unit. 
 
     
     
       6. The machine tool according to  claim 1 , wherein the display displays at least a side view of the machine tool. 
     
     
       7. The machine tool according to  claim 1 , wherein the machine tool is an injection molding machine. 
     
     
       8. The machine tool according to  claim 7 , wherein the display displays both the levelness in a direction parallel to an injection axis and the levelness in a direction perpendicular to the injection axis. 
     
     
       9. The machine tool according to  claim 7 , wherein the display displays an overhead view or a side view of only one of an injection unit and a clamping unit.
